How To Select The Proper Concrete Pavers For Your Projects?

The selection of the pavers depends directly on the type of the applications.

As a rule, interlock among pavers used for pedestrian areas and residential driveways is achieved with 2 3/8 in. (60 mm) thick units. For vehicular pavements including streets, industrial port and airport pavements, 3 1/8 in. (80 mm) thick pavers are used since loads are higher. Herringbone laying patterns should be used in these pavements, as they offer greater resistance to horizontal “creep” from turning, braking, and accelerating tires.

The Aspect Ratio Of Brick and Its Effect on Applications

There are many shapes and sizes of concrete unit paving available. They generally fall into two categories, interlocking concrete pavers and concrete paving slabs. You should should be aware of some principles that distinguish one product group from the other. These principles can help guide product selection and installation.

The rule of thumb for selecting the right size units for pedestrian and vehicular application depends on two important aspect ratios. One is the ratio of overall length to width, or plan ratio. If it is roughly between 2:1 and 3:1, the unit generally can be placed in an interlocking pattern. Interlocking patterns have proven to provide greater stability and structural support than other laying patterns when subjected to vehicular traffic.

The other important aspect ratio is the overall length of a unit to its thickness. When this ratio exceeds 4:1, units should not be used in streets and parking lots. Pavers having ratios between 3:1 and 4:1 generally can be used in residential drives. Figure above illustrates these differences. Units with length to thickness aspect ratios between 3:1 and 4:1 are generally not subject to flexing and cracking under vehicular loads. Those with an aspect ratio of 3:1 can be used in all vehicular applications. For example, pavers 4 in. by 8 in. by 3 1/8 in. (100 mm wide by 200 mm long by 80 mm thick) rectangular pavers have an aspect ratio of 200: 80 or 2.5:1. This makes them suitable for streets.

Users tend to confuse interlocking concrete pavers with paving slabs as being appropriate for the same applications. They are not. The thinner, larger paving slabs are not suited for vehicular traffic because they may flex and crack from loads. Interlocking concrete pavers, however, can be used in either vehicular or pedestrian applications.

When properly installed, interlocking concrete pavers are tightly fitted together with sand filled joints. The sand transfers loads to surrounding units, reducing the load on the compacted aggregate base and soil subgrade.

Interlocking concrete pavers have more vertical area on their sides to “lock up” and distribute loads to their neighbors.
